RADIATOR.

Specification of Letters Patent.

Patented liagv 3O To all whom it may concern:

Be it known that 1, JOHN ML Fnnnnns, a citizen of the United States, residing at Bufialo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following is a specification.

This invent-ion relates more particularly to a radiator which is designed to cool the Water which is used in the cooling system of gasolene engines or the like for automobiles.

One of the objects of this invention is to produce a radiator of this character which has a maximum cooling ellieiencyand which can be produced at comparatively low cost.

Another object of this invention is the production of a radiator of this character which will present comparatively heavy dividing walls between the several cells or conduits for the air at the ends thereof and still permitof employing comparatively thin metal in the body of the cells so as to obtain the highest cooling efliciency of the radiator.

In the accompanying drawings consisting of 2 sheets: Figure l is a front elevation of my improved radiator. Fig. 2 is a fragmentary vertical transverse section thereof, on an enlarged scale, taken in line 2-2, Fig. 3. Figs. 3 and l are vertical longitudinal sec tions, taken in the correspondingly numbered lines in Figs. 1 and 2. 5 and G are fragmentary horizontal sections taken in the correspondingly numbered lines in Figs. 1 and 2. F T is a l raginentarv perspective view showing two corrugated strips, plates or sections preparatory to assembling the same for producing a vertical. row or set of tubes.

Similar letters of reference indicate corresponding parts throughout the several views.

This radiator comprises generally a heat exchanging field containing a pluialilw of upright tortuous water channels, conduits or spaces a which connect at their upper ends with a water inlet manifold or header B, and at their lower end is a water outlet manifold or header C, a plurality of horizontal air tubes (Z arranged between the water channels and rear side of the radiator, and two upright side walls E arranged on opposite sides of the mass of tubes and connecting the upper and lower headers.

extending from the front to the The upper or inlet header is provided on its rear side or wall with the .sual inlet opening Z) connected with one side of the cooling system of the engine and the rear wall of the lower header is provided with an outlet opening 0 which is adapted to be connected in any suitable way so the other side of said cooling system.

The air tubes are arranged in vertical rows, the several tubes in each row being staggered laterally, preferably hall way with reference to the adjacent rows'ot' tubes so that the several tubes of the radiator pre sent an appearance at the front and rear of the radiator resembling that of radiators in which the cooling hold is produced by assembling a plurality of individual square tubes which are staggered with reference to each other and produce between them tortuous or zigzag water channels the turns of which are at right angles. 7

In the present radiator a plurality of pairs of upright strips, sheets or plates of thin metal are so corrugated that by i: bling a complementary pair of such strips in register with each other an upright tier or row of horizontal air tubes will be produced which staggered with reference to each other. Each of the sheet metal plates or strips of each pair is so corrugated to form a plurality of pairs of wide horizontal walls 7, a plinality of narrow horizontal walls g, the pairs of wide walls alternating with the pairs oi? narro ',walls and one of the edges of the several horizontal walls bein vertically in line while the other longi- .tiuiinal edges of the several narrow walls are a rrauged on a vertical line between the longil udinal edges of the wide walls, a plurality 7 t short vertical webs h which are arranged vertically in line and each of which connects the corresponding longitudinal edge of: one of the wide walls and the companion longi tudinal edge of the adjacent narrow wall which is vertically in line therewith, a .plurality of upright walls 5 which are arranged in line vertically and each of which connects those longitudinal edges of a. pair o't narrow horizontal walls opposite to the webs and a plurality of vertical walls j which are arranged in line vertically and alternate with the vertical walls and each of which connects those longitudinal edges of a company the same and. prevei'lt leakage.

said Webs. walls gis separated from the adjacent wide ion pair of wide horizontal walls opposite to Each of the narrow horizontal horizontal Wall by an intervening space equal to the length of the companion web and the several corrugated strips or plates are so assembled. that the webs thereof ongage with each other and each narrow horizontal wall of one strip is in line horizontally with one of the wide horizontal walls the upper to the lower end of the strip and follows the contour thereof in a direction at right angles to the corrugations The beads of the strips of adjacent rows of tubes abut against each other and are connected by solder or otherwise to seal the joint between v The beads of the tube sheets or strips are preferably arranged a short distance inwardly or brclr. from the verti al edges of the tube strips, so that upon assembling the several ro s of tubes tortuous outwardly opening grooves Z are formed between adjacent rows of tubes. lnto these grooves is placed a filling in con- 's is,ting preferably of solder which may be laced in the grooves. in any suitable way but preferably by d )ping the ends of the tube strips in molten solder. By this means the several rows oi tubes are not only reliably connected an leakage prevented but a wide line or heavy division ltietwcen. the several tubes is p. ,duccd which is very much sought after for the purpose of giving the radiator a very substantial and heavy appearance notwithstanding that the same is comparatively ligl-it, has a large cooling'capacity and can be produced at low cost coinpared with a radiator built up cl individual tubes.

I claim as my invention:

1. "Ar-radiator comprising a plurality of upright rows of horizontal tubes which are separated to form tortuous upright channels between the rows of tubes, each row oi tubes being staggered. and constructed. of two sheet metal strips each of which is corrugated to form alternating pairs of narrow horizontal walls and wide horizontal walls, said horizontal walls being vertically in line at one of their corresponding edges, upright webs each connecting the longitudinal edge of one narrow horizontal wall and the corresponding longitudinal edge which is vcrticallv in eeassa line therewith of an adjacent wide horizontal wall, plurality of upright walls arranged vertically in line and each connecting a pair of narrow horizontal walls at their corresponding longitudinal. edges opposite said web, and a plurality of upright walls arranged vertically in line and each connecting a pair of wide horizontal walls at their corresponding longitudinal edges opposite said web, the companion strips of a row of tubes having their webs engaging with each other and the narrow horizontal walls or" each strip being in line with the wide horizontal walls of the other strip.

2. A radiator comprising a plurality of upright rows of horizontal, tubes which are se iiarated to form tortuous upright channelsbctween the rows of tubes, each row of tubes being staggered and constructed of two sheet metal strips each of which is corrugated. to form alternating pairs of narrow horizontal walls and wide horizontal walls, said horizontal walls being vertically in line at one of their corresponding edges, upright webs each connecting the longitudinal edge of one narrow horizontal wall and the corresponding longitudinal edge which is vertically in line therewith of an adjacent widehorizontal wall, a plurality of upright walls arranged vertically in line and each connecting a pair of narrow horizontal walls at their corresponding longitudinal edges opposite said web, a plurality of upright walls arrangcal vertically in line and each connecting a pair of wide horizontal walls at their corresponding longitudinal edges opposit-c said web, the companion strips of a row of tubes havi their webs engaging with each oth r and the narrow horizontal walls of each strip being in line with the wide horizontal walls of the other strip, and beads arranged on the outer sides of said strips and engaging with each other.
